To v@ZZ whom t may concern: i

Be it known that 1, ALPHoNsUs FINN, a citizenof the United States, residing in the borough of Bronx, city and State of New York,l have invented certain new and useful Improvements in Metal Vindows, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof. l

This invention relates to the` construction of window frames formed of sheet metal and is particularly concerned with the construc-v tion at the corners, where the jambs, or ,-vertical members, and the head or lintel and sill, or horizontal members, meet. The objects of the invention are to reduce the cost of manufacture, to attain greater strength at the points of union of the vertical members and the horizontal members, andto improve the appearance. In accordance with the inf vention one of the members is formed at its end with tongues which are made to interlock with the adjacent portions of the other member, as by being bent over upon the edge of the other member or passed throughslots in the other member, or in both ways, a strong union of the twov members being secured in this manner without the use of vrivets and at greater reduced expense in labor. The effect, in appearance, of a mitered joint is secured by forming in the face of one member a diagonal slot and passing through it a broad tongue formed at the end of the corresponding face of the other member. The frame is stiffened, at the corner, by a brace which is so constructed as to form also a housing or support for the sash pulleys. The invention will be more fully explained hereinafter with io reference to the accompanying drawings in which it is illustrated and in which- Y Figure 1 is a view in vertical sectional elevation, on the plane indicated by thel broken line 1 1 of Figure 2, Vof the corner portion of a window frame constructed 1n accordance with the invention, yone of the interlocking tongues being Ashown `in the position'which it has before it is turned over i and smashed down. i VFigure 2 is a view of the same as seen in elevation from the right hand in Figure 1, the head or lintel being shown in section` on the plane indicated by the broken line ,f 2-2 of Figure 1.

Figure 10 is a view on line ,1()10- of Figure 2, looking to the right.

Figures 11, 12.I and 13 are vertical sectional views on lines 11-11, 12-12and 13-13, respectively, of Figure 10, and

Figure 14 is a, view in elevation` ofther corner construction from the outside look-k i ing to the left of Figure 3. d .y Theform of window frame in connection with which thepresent improvements haveA been developed is that in whichlthe vertical frame'member Or vjamb a is of sheet metal bent to form an enclosed weight box, havingH at its face a separable portion b which forms guideways and a parting strip forthe sashes and is held in place removably by screws b which' engage braces c and of heaviery material located within theweight box. The brace CZ, at the corner,` which forms the sup-4 porter housing for the sash pulleys as hereina-iter described, `is preferably securedl to the main `portion of the jamb by screwed" passed through the facek of the jamb.

The horizontal member, shown'here as the a and cl each extendsin full width to the.:

the outer vertical face of the si e member a meets the upper edge of the lintel member. This slot terminates at such distance from thisr corner as to leave a strip of sheet metal between it and the end of the member c,

' of substantial width, as shown in Figures 1, 3, 4, 10 and 14. Through this slot e is passed, from the outside, the tongue a. which is `formed on the kend portion of the. side member a vby deep cut or cleft it extending inward from ythe end of the end portion toa point g2 sonas to leave to the left of this cut or cleft h., as shown in Figure 14, a tab g3 relatively long, extending upward beyon the line of the upper edge of member e until it is folded down as hereinafter described. Tongue a thus formed is of less width than the member a and is adapted to lit the diagonal slot e. This tongue a is provided on its end with a tab or tabs, here shown as two in number, It"

and h2, extending upward a relatively short distance.

vThe lintel member e is provided along its upper edge with one or more preferably two as shown, tabs e2, relatively long, extending upward in position to be folded over the relatively short tabs L and k2 on` the end of tongue a of the side member, and hasv also, at its end a tab h3, relatively short and of a width corresponding with the width of tab g3 on the end of member a. l

When the members a and e are assembled by passing tongue 0; through slot e the tab g3 will extend upward, to the right in Figure 14, above the upper edge of member e, on the outside of the'outer end portion of member e and the relatively short tab h3 will lie against the inner face of this tab g?. The relatively short tabs it and 71,2 on the end of tongue a will lie against the inner faces of tabs e2 on the upper edge of member e. The lower or base portion of tongue a will be on the outside and the upper or terminal portion will be on the inside, of the member e.

The members a and e being thus assembled, the end of tab g3 is folded over onto tab 7b3 and the ends of tabs e2 are folded over onto tabs z. and 7b2. Tabs g3 and 71.3 are then folded inward on the line ofthe upper edge of member e and are compressed or smashed against the inner face of the end of member e thus interlocking the tabs together as is done in double seaming. Tabs e2 enclosing tabs it and 71.2 are then folded inward in the same way and are compressed or smashed against the inner face of the end portion of tongue a. By this double seaming together of the tabs the end portions of members t and e are so locked together that there can be no movement of one on the other and, at the same time the end portion of the tongue a" is held so closely against the member e that no moisture can enter between them.- If desired the end portions of the members a and e may be secured together by spot welding.

The effect to the-eye, of the construction described is that of a mitre joint as shown in Figure 14.

The back wall a? of the frame member a may also be formed, if desired, with a tab a3 which may be utilized in securing the top or cover, not shown, of the head or lintel e.

The opposite side a4 of the frame member at is also carried above the finished top line of the frame member e to form a tab or tabs a5 which, in like manner as previously described, and as shown in the right hand in Figures 7, S and 9, are each folded over upon a relatively shorttongue c5, extended above theupper finish line of the member e so as to enclose it, and, with the relatively short tab thus enclosed, is again bent or folded inward against the inner face of the member e to thus form a double seam or interlocled joint extended above the upper finish line of the member e and are bent or lapped over uponv and with the same and'hainmered or smashed, as shown in Figure 9, to malgre a firm union at the side. Y y

In the construction shown the vertical and horizontal members are each, formed of a single strip of relatively thin sheet metal bent longitudinally to form inner and outer face portions and a central portion. connecting the face portions. In the vertical member a the central portion forms the back wall a2 connecting the outer edges of the face portions and between the inner edges of the face portions, that is the edges adjacent to the window sash, is the opening in which is secured the separable portion Z). In the horizontal member e, on the other hand, the cen" tral portion between the inner and outer face portions extends between the inner edges of these face portions. that is the edges adjacent to the window sash.

The horizontal or lintel member e is formed, on the face portion opposite that on which is formed the corner construction .above described, with a rabbet e and the mitre joint. The outer, or upper,.wall of rabbet e is provided at its end with an upturned, relatively short Vtab e8 and,at a point opposite the inner wall of rabbet al", is .pro-V vided with a transverse slot e7. The outer, or rear, wall of rabbet al -is provided at its end with a relatively long tab as of such length as to .permit itsend portion to be folded over onto the relatively short tab e8 so as to enclose it. After it is thus folded. over onto tab e8 the two vtabs are together, folded over lonto the upper wall of rabbet e6.

The inner wall of rabbet al is provided at its .end with a tongue aiadapted -to be passed through t-he transverse slot e7 and of such length that when passed through the slot and bent down against the upper wall of rabbet c it will extend to the base of tab es terlocked tabs aS and es. The rabbets e and f 01 are thus iirmly locked together.

The brace el, above referred to. not .only serves to stiften the member a at the .corners and to form-.a support for the under side of the head or Slintel 4e by lmeans `of an ear e formed integral with the vunder sid@ of the head .or lintel from which it is bent downward at right angles and lsecured to Abrace d by a screw el", but it serves also as a support and housing forthesash pulleys; As shown', the brace (l is carried well above* the level `of under side of thel head or lintel c and is bent` as at cl2, to form a .seat for the reception of the inner ends Aof the two spindles f upon: which are mounted lthe sash pulleys f. The two sipndles, Iindependent of each other to facilitate `replacement in case of necessity, are clamped in the 4head d" by a plate .d3 which is indented, as at Clt, to hold .the spindles apart and permit longitudinal movement when theplate Z3 Vis removed. .the plate Z3 being secured. tothe .plate d by a screw d5 which is passed through the indented portion of the plate d3 and is threaded into the indented portiond2 of the plated. Should. it be necessary at any time to renew either sash pulley or its spindles, the face plate b yof the jamb `is removed,the screws d and .elo are withdrawn and the brace is `lowered within the jamb suiiciently vto permit the screw det to be withdrawn and the spindles released for substitution or adjustment or repair.

It will be understood that various cha-nzgcs can be made in details of construction and arrangement and that the invention, except as pointed out in the claims, is not restricted to the particular construction shown and described herein.
